HTML 4.0 Table Column Proportional Width Constraints

The table below is 350 pixels wide. The columns are assigned proportional widths using COLs
as follows:

<col width=50>
<col width=2*>
<col width=1*>
<col width=3*>

This means the first column should be 50 pixels wide. The remaining width should be divided
among the three remaining columns according to the proportional width statements into six
(2+1+3)
parts. Since the Table is 350 pixels wide, and the remaining width is 300 pixels (350-50),
the remaining columns should be 100 (2*50), 50 (1*50) and 150 (3*50) pixels wide,
respectively.
